Description

この発明は、互いに隣り合う壁パネルの間に形成された目地を閉塞する壁目地の防水構造に関する。   The present invention relates to a waterproof structure for a wall joint that closes a joint formed between adjacent wall panels.

従来、下記特許文献１に開示されるように、互いに隣り合う外壁パネルの間に形成された目地を閉塞する乾式の目地構造が知られている。この発明は、隣接する外壁パネルに跨って目地を閉塞する目地蓋部と、目地蓋部の内側面中央から突設する挿入部と、挿入部の左右に突設されて壁パネルの小口面に当接するヒレ部と、を一体に形成した目地材を、屋外側から目地に圧入することで目地内部に水が浸入することを防止できる。また、目地材は、目地材の屋内側に配置され、挿入部に外嵌するとともに外壁パネルの屋内側の端縁に係止する目地材保持具によって外壁からの脱落を防止している。   Conventionally, as disclosed in Patent Document 1 below, a dry joint structure that closes joints formed between adjacent outer wall panels is known. The present invention includes a joint cover portion that closes the joint across adjacent outer wall panels, an insertion portion that protrudes from the center of the inner surface of the joint cover portion, and a left and right portion of the insertion portion that protrudes from the left and right sides of the insertion portion. It is possible to prevent water from entering the joint by press-fitting the joint material formed integrally with the fin portion that comes into contact with the joint from the outdoor side. Further, the joint material is disposed on the indoor side of the joint material, and is prevented from falling off the outer wall by a joint material holder that is fitted on the insertion portion and is engaged with the indoor side edge of the outer wall panel.

また、特許文献２に記載されている防水構造は、屋外に面する蓋部と外壁パネルの小口面に圧接する襞とを有した一次シール部材と、一次シール部材の屋内側に形成される第２突起に嵌着するクリップ部材と、クリップ部材に外嵌し、外壁パネルの屋内側の端縁に圧接する二次防水部材と、を備えており、各部材は別体で構成されている。弾性樹脂で形成される一次シール部材及び二次防水部材は、クリップ部材を介して互いに嵌着することにより一体として使用することができ、一体化されたこれらの部材を目地に圧入することで目地内部への水の浸入を防止することができる。   In addition, the waterproof structure described in Patent Document 2 is formed on the indoor side of the primary seal member having a lid portion that faces the outside and a ridge that presses against the small edge surface of the outer wall panel. And a secondary waterproofing member that is externally fitted to the clip member and press-contacted to the indoor side edge of the outer wall panel, and each member is configured separately. The primary seal member and the secondary waterproof member formed of elastic resin can be used as a single unit by being fitted to each other via a clip member, and the joint is press-fitted into the joint. It is possible to prevent water from entering the inside.

しかしながら、特許文献１に記載の目地材は、目地蓋部、挿入部、及びヒレ部が一体成形されているので、複雑な形状を製造するために大掛かりな製造設備が必要となり、ある程度の出荷数量を保持しなければ設備維持費用が増大するという問題点が挙げられる。さらに、それぞれの部位に期待される機能に応じて材質を変更することが難しく、また、部位ごとに材質を変更できたとしても、廃棄時に各材質ごとに分別することができず、部材の再資源化を行うことができない。   However, the joint material described in Patent Document 1 has a joint cover part, an insertion part, and a fin part, which are integrally formed. Therefore, a large-scale manufacturing facility is required to manufacture a complicated shape, and a certain amount of shipment is required. If this is not maintained, the equipment maintenance cost increases. Furthermore, it is difficult to change the material according to the function expected for each part, and even if the material can be changed for each part, it cannot be separated for each material at the time of disposal, and the parts can be reused. It cannot be recycled.

また、特許文献２の目地構造では、一次シール部材と二次防水部材とが別体で形成されるものの、やはり一次シール部材の蓋部と襞とを一体成形しているため各部位の機能に応じて材質を変えることが容易ではない。また、クリップ部材は、一次シール部材と二次防水部材とを連結するためだけのものであるため、弾性樹脂で形成された一次シール部材及び二次防水部材が経年劣化によって痩せた場合、両部材が縦目地から脱落する虞がある。   Moreover, in the joint structure of patent document 2, although the primary sealing member and the secondary waterproofing member are formed separately, since the lid part of the primary sealing member and the heel are also integrally formed, the function of each part is improved. It is not easy to change the material accordingly. In addition, since the clip member is only for connecting the primary seal member and the secondary waterproof member, both members when the primary seal member and the secondary waterproof member formed of elastic resin are thin due to deterioration over time. May fall out of the vertical joint.

そこで、本発明は、上述した課題を鑑みてなされたものであり、互いに隣り合う壁パネルの間に形成される目地を閉塞する壁目地の防水構造であって、各部位の機能に応じて容易に材質の変更が可能であるとともに、製造コストを抑制することができる構造を提供することを目的とする。   Accordingly, the present invention has been made in view of the above-described problems, and is a waterproof structure for a wall joint that closes joints formed between adjacent wall panels, and can be easily adapted to the function of each part. It is an object of the present invention to provide a structure that can change the material and can reduce the manufacturing cost.

本発明の第１の壁目地の防水構造は、互いに隣接する壁パネルの間に形成された目地を閉塞する壁目地の防水構造であって、前記目地の幅よりも幅広に形成されて前記隣接する壁パネルの化粧面に跨る蓋部を有し、前記目地の長手方向へ延びる１次止水材と、前記蓋部の壁内側の面から壁内方向へ延びる第１突出部に嵌合し、幅方向の両端部にヒレ状のヒレ部を形成して前記目地の内部に圧入される前記目地の長手方向へ延びる２次止水材と、前記ヒレ部の基端から壁内方向へ延びる第２突出部に外嵌する一対の嵌着部と、前記壁パネルの小口面に弾性的に係止する一対の係止部とを有する保持クリップと、を備えることを特徴としている。   The waterproof structure of the first wall joint of the present invention is a waterproof structure of the wall joint that closes the joint formed between the adjacent wall panels, and is formed wider than the width of the joint, and is adjacent to the adjacent joint. A lid that straddles the decorative surface of the wall panel to be engaged, and is fitted to a primary water stop material extending in the longitudinal direction of the joint, and a first protrusion extending inward from the inner wall surface of the lid. A secondary water-stopping material extending in the longitudinal direction of the joint formed by forming a fin-like fin at both ends in the width direction, and extending from the proximal end of the fin inward into the wall A holding clip having a pair of fitting portions that are externally fitted to the second projecting portion and a pair of locking portions that are elastically locked to the small edge surface of the wall panel is provided.

本発明の第２の壁目地の防水構造は、前記第１突出部は、前記目地の幅方向の両側面に一対の第１突起を少なくとも１以上形成し、前記第２突出部は、前記蓋部側の面から壁内方向へ延びるとともに内側面から突出して互いに対向する一対の第２突起を設けた溝を形成しており、前記一対の第２突起の先端同士の距離は、前記一対の第１突起の先端同士の距離以下であることを特徴としている。   In the waterproof structure of the second wall joint according to the present invention, the first protrusion includes at least one pair of first protrusions on both side surfaces in the width direction of the joint, and the second protrusion includes the lid. A groove is formed that extends inward from the surface of the portion side and protrudes from the inner surface and is provided with a pair of second protrusions facing each other, and the distance between the tips of the pair of second protrusions is It is characterized by being less than or equal to the distance between the tips of the first protrusions.

本発明の第３の壁目地の防水構造は、前記一対の嵌着部は、前記蓋部の方向へ延びて略平行に対向する一対の板片と、前記一対の板片の互いに対向する面から壁内方向へ斜めに突設する一対の返し片と、を形成し、前記第２突出部は、前記目地の幅方向の両側面に一対の窪みを形成しており、前記一対の返し片の先端同士の距離は、前記第２突出部の前記窪みの位置の幅と略同一に形成されることを特徴としている。   In the waterproof structure of the third wall joint of the present invention, the pair of fitting portions extend in the direction of the lid portion and face each other in a substantially parallel manner, and the pair of plate pieces face each other. A pair of return pieces projecting obliquely inward from the wall, and the second projecting portion forms a pair of depressions on both side surfaces in the width direction of the joint, and the pair of return pieces The distance between the tips of the second protrusions is formed to be substantially the same as the width of the position of the recess of the second protrusion.

本発明の第４の壁目地の防水構造は、前記第２突出部が、前記ヒレ部よりも高い剛性を有することを特徴としている。   The waterproof structure of the fourth wall joint according to the present invention is characterized in that the second projecting portion has higher rigidity than the fin portion.

本発明の第５の壁目地の防水構造は、前記蓋部は、幅方向の両端部を壁内方向へ向けて斜めに屈曲し、前記ヒレ部は、先端部を壁内方向へ向けて斜めに屈曲することを特徴としている。   In the fifth wall joint waterproof structure according to the present invention, the lid portion is bent obliquely with both widthwise end portions directed inward of the wall, and the fin portion is inclined with the tip portion directed inward of the wall. It is characterized by bending.

本発明の第１の壁目地の防水構造によると、１次止水材及び２次止水材は、別体で形成されるので各止水材を従来よりも単純な材質や形状で製作することができ、製造コストを抑制することができる。また、各止水材は、異なる材質とすることができるので、それぞれの止水材の材質を、設置される部位を考慮した略同様の耐久年数となる材質にすることにより、メンテナンス時期を一致させた合理的な防水構造を構築することができる。また、保持クリップが２次止水材に外嵌することにより、保持クリップが２次止水材の第２突出部を押圧するため、１次止水材と２次止水材との固定強度を向上させることができる。したがって、各止水材同士の嵌合部分の強度を低く抑えることができ、各止水材同士の組み立て作業を容易に行うことができるとともに１次止水材に嵌合する２次止水材の材質の選択肢を広げることができる。   According to the waterproof structure of the first wall joint of the present invention, the primary waterproof material and the secondary waterproof material are formed separately, so that each waterproof material is manufactured with a simpler material and shape than before. Manufacturing cost can be reduced. In addition, each water-stopping material can be made of a different material, so the maintenance time is matched by making each water-stopping material a material that has substantially the same durable life considering the installation site. A reasonable waterproof structure can be constructed. In addition, since the holding clip presses the second protruding portion of the secondary water-stopping material by fitting the holding clip to the secondary water-stopping material, the fixing strength between the primary water-stopping material and the secondary water-stopping material Can be improved. Therefore, the strength of the fitting portion between the water-stopping materials can be kept low, the assembly work between the water-stopping materials can be easily performed, and the secondary water-stopping material fitted into the primary water-stopping material. The choice of materials can be expanded.

本発明の第２の壁目地の防水構造によると、第２突出部の一対の第２突起の先端同士の距離は、第１突出部の第１突起の先端同士の距離以下であるため、第２突出部の溝に第１突出部を押し込み嵌め合わせると、第２突起が抜け止めとなって第１突出部が溝から抜けることを防止できる。したがって、１次止水材を２次止水材に押し込み嵌め合わせるだけで２つの止水材を一体とすることができ、容易に組み立て作業を行うことができる。   According to the waterproof structure of the second wall joint of the present invention, the distance between the tips of the pair of second protrusions of the second protrusion is equal to or less than the distance between the tips of the first protrusions of the first protrusion. When the first protrusion is pushed in and fitted into the groove of the two protrusions, the second protrusion is prevented from coming off and the first protrusion can be prevented from coming out of the groove. Therefore, the two water-stopping materials can be integrated by simply pressing and fitting the primary water-stopping material to the secondary water-stopping material, and the assembly work can be easily performed.

本発明の第３の壁目地の防水構造によると、一対の返し片の先端同士の距離は、第２突出部の窪みの位置の幅とほぼ同一に形成されるので、一対の嵌着部の間に２次止水材を押し込むと、窪みに返し片が係止して２次止水材が保持クリップから外れることを防止できる。したがって、２次止水材を保持クリップに押し込むだけで２つの部材を一体とすることができ、容易に組み立て作業を行うことができる。   According to the waterproof structure of the third wall joint of the present invention, the distance between the tip ends of the pair of return pieces is formed to be substantially the same as the width of the position of the recess of the second projecting portion. When the secondary water-stopping material is pushed in between, the return piece is locked in the recess and the secondary water-stopping material can be prevented from coming off the holding clip. Therefore, the two members can be integrated by simply pushing the secondary water stop material into the holding clip, and the assembly operation can be easily performed.

本発明の第４の壁目地の防水構造によると、第２突出部は、ヒレ部よりも高い剛性を有するので、ヒレ部と同じ材質を使用したときよりも、１次止水材と２次止水材との嵌め合わせを強化することができる。したがって、１次止水材が２次止水材から抜けにくくなり安定した壁目地の防水構造を構築することができる。   According to the waterproof structure of the fourth wall joint of the present invention, the second protruding portion has higher rigidity than the fin portion, so that the primary water-stopping material and the secondary material are used more than when the same material as the fin portion is used. The fitting with a water stop material can be strengthened. Therefore, it becomes difficult for the primary water-stopping material to come off from the secondary water-stopping material, and a stable wall joint waterproof structure can be constructed.

本発明の第５の壁目地の防水構造によると、蓋部は、幅方向の両端部を壁内方向へ向けて斜めに屈曲し、ヒレ部は、先端部を壁内方向へ向けて斜めに屈曲しているので、壁パネルと各止水材との間に隙間を形成することがなく、壁内部への水の浸入を防止することができる。   According to the waterproof structure of the fifth wall joint of the present invention, the lid portion is bent obliquely with both end portions in the width direction facing in the wall direction, and the fin portion is slanted with the tip portion directed in the wall direction. Since it is bent, no gap is formed between the wall panel and each water blocking material, and water can be prevented from entering the wall.

以下、壁目地の防水構造の最良実施形態について各図を参照しつつ説明する。本願の壁目地の防水構造は、主に外壁である壁パネル間に形成される縦目地に使用されるが、壁パネル同士の目地であれば屋内外問わず使用することができる。ここでは、壁パネルが外壁である場合について説明を行う。また、本願において「壁内」とは、壁パネルを支持する躯体が位置する壁内部の空間のことを指す。   Hereinafter, the best embodiment of the waterproof structure of the wall joint will be described with reference to the drawings. The waterproof structure of the wall joint of the present application is mainly used for a vertical joint formed between wall panels which are outer walls, but can be used both indoors and outdoors as long as the joint between the wall panels. Here, the case where a wall panel is an outer wall is demonstrated. Further, in the present application, “inside the wall” refers to a space inside the wall in which the housing supporting the wall panel is located.

図１に示すように、壁目地の防水構造１は、互いに隣接する壁パネル２の間に形成された目地３を閉塞する構造であって、目地の幅Ｗ１よりも幅広に形成されて隣接する壁パネル２の化粧面２１に跨る蓋部４ａを有する１次止水材４と、蓋部４ａの壁内側の面から壁内方向へ延びる第１突出部４ｂに嵌合し、幅方向の両端部にヒレ状のヒレ部５ａを形成して目地３の内部に圧入される２次止水材５と、ヒレ部５ａの基端から壁内方向へ延びる第２突出部５ｂに外嵌する一対の嵌着部６ａ、及び壁パネル２の小口面２ａに弾性的に係止する一対の係止部６ｂとを有する保持クリップ６と、を備える。   As shown in FIG. 1, the waterproof structure 1 of the wall joint is a structure that closes the joint 3 formed between the wall panels 2 adjacent to each other, and is formed adjacent to the width W1 of the joint. The primary waterproofing material 4 having the lid portion 4a straddling the decorative surface 21 of the wall panel 2 and the first projecting portion 4b extending inward from the inner wall surface of the lid portion 4a are fitted to both ends in the width direction. A pair of second waterstop 5 that is formed into a fin-like fin portion 5a and press-fitted into the joint 3, and a second protruding portion 5b that extends inward from the base end of the fin portion 5a. And a holding clip 6 having a pair of locking portions 6b that are elastically locked to the small edge surface 2a of the wall panel 2.

図１に示す壁パネル２は、外壁材の一例を示すものである。壁パネル２は、外部に面する平板状の部材で、壁内側の面の端部には、溝を壁パネル２の側方向へ開く溝形鋼で形成されたフーレム材２２が固定されている。なお、壁パネル２は、図１の形に限定されることはなく、押出成形セメント板や軽量気泡コンクリートのように厚みのある壁部材であってもよい。互いに隣接する壁パネル２は、同一平面となるように配置され、互いに水平方向へ間隔を空けて柱や間柱などの躯体７に図示しない従来公知の固定金具で固定される。図示するように、壁パネル２同士の間には目地３が形成され、この目地の幅Ｗ１は、壁パネル２の種類や形状に応じた所定の幅で形成される。   The wall panel 2 shown in FIG. 1 shows an example of an outer wall material. The wall panel 2 is a flat plate-like member facing the outside, and a frame material 22 made of channel steel that opens the groove in the lateral direction of the wall panel 2 is fixed to the end of the inner wall surface. . The wall panel 2 is not limited to the shape shown in FIG. 1 and may be a thick wall member such as an extruded cement board or lightweight cellular concrete. The adjacent wall panels 2 are arranged so as to be on the same plane, and are fixed to a housing 7 such as a pillar or a stud with a conventionally well-known fixing metal (not shown) at an interval in the horizontal direction. As illustrated, a joint 3 is formed between the wall panels 2, and the joint width W <b> 1 is formed with a predetermined width corresponding to the type and shape of the wall panel 2.

図１及び図２に示すように、１次止水材４は目地３の長手方向へ延びる長尺な部材で、略平板状に形成され、隣接する壁パネル２の化粧面２１に跨る蓋部４ａと、蓋部４ａの壁内側の面の幅方向略中央から壁内方向へ延びる第１突出部４ｂと、によって構成される断面視略Ｔ字形の部材である。第１突出部４ｂは、目地３の幅方向の両側面に一対の第１突起４１を設けており、また、蓋部４ａは、幅方向の両端部を壁内方向へ向けて斜めに若干屈曲している。そして蓋部の幅である第１幅Ｗ２は、目地の幅Ｗ１よりも幅広に形成される。なお、図示例では、第１突起４１を２箇所設けているが、その数は１箇所以上であれば特に限定されない。   As shown in FIGS. 1 and 2, the primary water blocking material 4 is a long member extending in the longitudinal direction of the joint 3, is formed in a substantially flat plate shape, and covers a decorative surface 21 of the adjacent wall panel 2. 4a and a first projecting portion 4b extending in an inward direction from the center in the width direction of the inner surface of the lid portion 4a. The first protrusion 4b is provided with a pair of first protrusions 41 on both side surfaces of the joint 3 in the width direction, and the lid portion 4a is slightly bent obliquely with both end portions in the width direction directed toward the in-wall direction. doing. The first width W2 that is the width of the lid portion is formed wider than the joint width W1. In the illustrated example, two first protrusions 41 are provided, but the number is not particularly limited as long as the number is one or more.

図１に示すように、１次止水材４は目地３に設置した際に、直接外気に触れる部材である。その材質は、耐候性及び耐久性に優れたものであれば特に限定されないが、本実施例のように外壁に使用する場合は、上述の機能を有するとともに壁パネル２と共通の塗装を施しやすい金属材料、例えば、アルミ形材が好適である。なお、１次止水材４を金属材料のように硬質な材料とした場合は、壁パネル２の化粧面２１を凹凸の無いものとした方が安定した防水性能を保持することができる。   As shown in FIG. 1, the primary water blocking material 4 is a member that directly contacts outside air when installed on the joint 3. The material is not particularly limited as long as it is excellent in weather resistance and durability, but when used on the outer wall as in this embodiment, it has the above-described function and can be easily painted in common with the wall panel 2. Metal materials, such as aluminum profiles, are preferred. In addition, when the primary water blocking material 4 is made of a hard material such as a metal material, a stable waterproof performance can be maintained if the decorative surface 21 of the wall panel 2 has no unevenness.

図１及び図２に示すように、２次止水材５は目地３の長手方向へ延びる長尺な部材で、幅方向の両端部にそれぞれ形成された長尺なヒレ状のヒレ部５ａと、ヒレ部５ａの幅方向の基端から壁内方向へ突出し、１次止水材４の第１突出部４ｂに嵌合する断面視略Ｕ字形の第２突出部５ｂと、によって構成される。また、２つのヒレ部５ａの先端同士の幅である第２幅Ｗ３は、目地の幅Ｗ１よりも幅広に形成されている。   As shown in FIGS. 1 and 2, the secondary waterproofing material 5 is a long member extending in the longitudinal direction of the joint 3, and has a long fin-shaped fin portion 5 a formed at both ends in the width direction. The second projecting portion 5b having a substantially U-shaped cross-sectional view and projecting inward from the base end in the width direction of the fin portion 5a and fitting into the first projecting portion 4b of the primary water blocking material 4 is configured. . The second width W3, which is the width between the tips of the two fin portions 5a, is formed wider than the joint width W1.

第２突出部５ｂは、目地３の長手方向へ延びる長尺な部材で、蓋部４ａ側の面から壁内方向へ延びる溝５１を形成している。この溝５１には、内側面から突出して互いに対向し、１次止水材４の一対の第１突起４１に係止する一対の第２突起５２が設けられている。図５に示すように、この一対の第２突起５２の先端同士の距離である第３幅Ｗ３ａは、一対の第１突起４１の先端同士の距離である第４幅Ｗ２ａ以下に形成される。なお、図示例では、一対の第２突起５２が一対の第１突起４１と同数設けられているが、一対の第２突起５２の数を一対の第１突起４１よりも多く設置してもよい。また、第２突出部５ｂの両外側面には、保持クリップ６の嵌着部６ａに外嵌される一対の窪み５３が形成されている。ヒレ部５ａは、幅方向の基端から先端に向けてその厚さを若干薄く形成しており、また、その先端部は壁内方向へ斜めに若干屈曲している。   The 2nd protrusion part 5b is the elongate member extended in the longitudinal direction of the joint 3, and forms the groove | channel 51 extended in the wall inner direction from the surface by the side of the cover part 4a. The groove 51 is provided with a pair of second protrusions 52 that protrude from the inner surface and face each other and engage with the pair of first protrusions 41 of the primary water blocking material 4. As shown in FIG. 5, the third width W <b> 3 a that is the distance between the ends of the pair of second protrusions 52 is formed to be equal to or less than the fourth width W <b> 2 a that is the distance between the ends of the pair of first protrusions 41. In the illustrated example, the same number of the pair of second protrusions 52 as the pair of first protrusions 41 is provided. However, the number of the pair of second protrusions 52 may be larger than that of the pair of first protrusions 41. . In addition, a pair of recesses 53 that are externally fitted to the fitting portions 6 a of the holding clip 6 are formed on both outer side surfaces of the second projecting portion 5 b. The fin portion 5a is formed such that its thickness is slightly reduced from the base end in the width direction toward the tip, and the tip portion is slightly bent obliquely inward in the wall.

２次止水材５は、弾性及び水密性を有する樹脂によって形成される。より具体的には、第２突出部５ｂの材質は、１次止水材４の第１突出部４ｂ及び保持クリップ６の嵌着部６ａと嵌合可能な程度の剛性を有する、特に熱硬化性の硬質樹脂や熱可塑性の硬質樹脂が好適である。また、ヒレ部５ａの材質は、熱硬化性樹脂系エラストマや熱可塑性樹脂系エラストマで形成された軟質樹脂が好適である。このように、第２突出部５ｂの材質をヒレ部５ａよりも高剛性とすることにより、第２突出部５ｂがヒレ部５ａよりも先に磨耗して１次止水材４及び保持クリップ６から脱落するという事態が防ぐことができ、安定した壁目地の防水構造１を構築することができる。なお、第２突出部５ｂ及びヒレ部５ａは、上述の機能を満たしていれば全く同様の材質としてもよい。   The secondary water blocking material 5 is formed of a resin having elasticity and water tightness. More specifically, the material of the second projecting portion 5b has a rigidity that can be fitted to the first projecting portion 4b of the primary waterstop material 4 and the fitting portion 6a of the holding clip 6, in particular, thermosetting. A hard resin and a thermoplastic hard resin are suitable. In addition, the material of the fin portion 5a is preferably a soft resin formed of a thermosetting resin-based elastomer or a thermoplastic resin-based elastomer. Thus, by making the material of the 2nd protrusion part 5b more rigid than the fin part 5a, the 2nd protrusion part 5b is worn out before the fin part 5a, and the primary water stop material 4 and the holding clip 6 are used. Can be prevented from falling off, and a stable wall joint waterproof structure 1 can be constructed. The second projecting portion 5b and the fin portion 5a may be made of the same material as long as the above-described functions are satisfied.

図３及び図４に表れるように、保持クリップ６は１枚の金属板の両端部を折曲して形成した金具である。保持クリップ６は、図１に示すように、２次止水材５の第２突出部５ｂに外嵌する一対の嵌着部６ａと、壁パネル２の小口面２ａに弾性的に係止する一対の係止部６ｂと、嵌着部６ａ及び係止部６ｂの基端を共通して壁内方向へ突出する溝状の基端部６ｃと、を有する。   As shown in FIGS. 3 and 4, the holding clip 6 is a metal fitting formed by bending both ends of a single metal plate. As shown in FIG. 1, the holding clip 6 is elastically locked to a pair of fitting portions 6 a that are externally fitted to the second projecting portion 5 b of the secondary water-stopping material 5, and the small edge surface 2 a of the wall panel 2. It has a pair of latching | locking part 6b, and the groove-shaped base end part 6c which protrudes in the wall inward in common with the base end of the fitting part 6a and the latching | locking part 6b.

一対の嵌着部６ａは、図３及び図４に示すように、係止部６ｂの長手方向における両側に一対ずつ形成されている。一対の嵌着部６ａは、それぞれ基端部６ｃを互いに離反する方向へ折曲した一対の第１板片６１と、第１板片６１の先端を基端部６ｃと反対側の方向へ折曲し、蓋部４ａの方向へ延びて略平行に対向する一対の第２板片６２と、一対の第２板片６２の互いに対向する面から基端部６ｃの方向へ略斜めに突設する一対の返し片６３と、によって構成されている。なお、図５に示すように、一対の返し片６３の先端同士の距離である第５幅Ｗ４ａは、第２突出部５ａの窪み５３の位置の幅である第６幅Ｗ３ｂと略同一に形成されている。   As shown in FIGS. 3 and 4, the pair of fitting portions 6 a are formed in pairs on both sides in the longitudinal direction of the locking portion 6 b. The pair of fitting portions 6a includes a pair of first plate pieces 61 that are bent in directions in which the base end portions 6c are separated from each other, and a front end of the first plate piece 61 is bent in a direction opposite to the base end portion 6c. A pair of second plate pieces 62 that bend and extend in the direction of the lid portion 4a and face each other substantially in parallel, and project substantially obliquely in the direction of the base end portion 6c from the mutually opposing surfaces of the pair of second plate pieces 62 And a pair of return pieces 63. As shown in FIG. 5, the fifth width W4a, which is the distance between the tips of the pair of return pieces 63, is formed substantially the same as the sixth width W3b, which is the width of the recess 53 of the second protrusion 5a. Has been.

一対の係止部６ｂは、図１及び図３に示すように、基端部６ｃから蓋部４ａの方向へ延びて互いに対向するバネ板状の一対の弾性板６４と、弾性板６４の先端部を折曲して形成され、壁パネル２の小口面２ａに引掛ける一対の引掛片６５と、によって構成されている。一対の弾性板６４は、基端部６ｃから互いに離反する方向へ斜めに突設するとともに、基端と先端の略中間で互いに近接する方向へ斜めに屈曲してバネ板状に形成される。また、この一対の弾性板６４の屈曲部分の幅である第７幅Ｗ４及び一対の引掛片６５の幅である第８幅Ｗ５は、目地の幅Ｗ１よりも広く形成されている。   As shown in FIGS. 1 and 3, the pair of locking portions 6 b includes a pair of spring plate-like elastic plates 64 extending from the base end portion 6 c in the direction of the lid portion 4 a and facing each other, and the distal ends of the elastic plates 64. It is formed by a pair of hook pieces 65 formed by bending a portion and hooked on the small edge surface 2a of the wall panel 2. The pair of elastic plates 64 project obliquely in a direction away from the base end portion 6c, and are bent obliquely in a direction close to each other at substantially the middle between the base end and the tip, and are formed in a spring plate shape. The seventh width W4, which is the width of the bent portion of the pair of elastic plates 64, and the eighth width W5, which is the width of the pair of hook pieces 65, are formed wider than the joint width W1.

これらの１次止水材４、２次止水材５、及び保持クリップ６は、図５及び図６に示すように、互いに嵌め合わせることによって一体の部材とすることができる。具体的には、まず、１次止水材４の第１突出部４ｂを２次止水材５の溝５１に押し込んで嵌め合わせる。このとき、先述したように、第３幅Ｗ３ａは、第４幅Ｗ２ａ以下に形成されるので、第２突起５２が抜け止めとなって第１突出部４ｂが溝５１から抜けることを防止できる。   As shown in FIGS. 5 and 6, the primary water-stopping material 4, the secondary water-stopping material 5, and the holding clip 6 can be integrated with each other as shown in FIGS. 5 and 6. Specifically, first, the first protrusion 4 b of the primary water blocking material 4 is pushed into the groove 51 of the secondary water blocking material 5 to be fitted. At this time, as described above, since the third width W3a is formed to be equal to or smaller than the fourth width W2a, it is possible to prevent the second protrusion 52 from coming off and the first protrusion 4b from coming out of the groove 51.

そして、保持クリップ６の一対の嵌着部６ａを２次止水材５の第２突出部５ｂに外側から嵌め込み、返し片６３を窪み５３に係合させ、各部材を一体とする。先述したように、第５幅Ｗ４ａは、第６幅Ｗ３ｂと略同一であるため、返し片６３が抜け止めとなって第２突出部５ｂが嵌着部６ａから抜けることを防止できる。また、図７に示すように、保持クリップ６を２次止水材５に外嵌すると係止部６ｂがヒレ部５ａを押圧するため、ヒレ部５ａは部分的に湾曲する。なお、保持クリップ６は、２次止水材５に少なくとも１以上設置すればよい。   Then, the pair of fitting portions 6a of the holding clip 6 are fitted into the second projecting portion 5b of the secondary waterstop material 5 from the outside, the return piece 63 is engaged with the recess 53, and the members are integrated. As described above, since the fifth width W4a is substantially the same as the sixth width W3b, it is possible to prevent the second protruding portion 5b from coming out of the fitting portion 6a by preventing the return piece 63 from coming off. Further, as shown in FIG. 7, when the holding clip 6 is externally fitted to the secondary waterproofing material 5, the locking portion 6b presses the fin portion 5a, so that the fin portion 5a is partially curved. In addition, what is necessary is just to install the holding | maintenance clip 6 in the secondary water stop material 5 at least 1 or more.

このように２次止水材５に保持クリップ６を外嵌することにより、１次止水材４が２次止水材５から外れようとすると、第１突出部４ｂ及び第２突出部５ｂの嵌合部分だけでなく嵌着部６ａ及び第２突出部５ｂの嵌合部分にも抵抗する力が発生するので、１次止水材４及び２次止水材５の固定強度を向上することができる。したがって、１次止水材４及び２次止水材５の嵌合部分の強度を比較的低く抑えることができ、各止水材４、５同士の組み立て作業を容易に行うことができる。また、各止水材４、５及び保持クリップ６は、工場で予め一体化しておき、工事現場での施工手間を省略してもよい。この場合、各部材は嵌合しているので各止水材４、５が運搬時に長手方向へずれたり、１次止水材４が２次止水材５から外れるという虞がない。   When the primary water stop material 4 is about to come off from the secondary water stop material 5 by fitting the holding clip 6 to the secondary water stop material 5 in this way, the first protrusion 4b and the second protrusion 5b. Since the force which resists not only the fitting part of this but also the fitting part of the fitting part 6a and the 2nd protrusion part 5b generate | occur | produces, the fixed strength of the primary waterproofing material 4 and the secondary waterproofing material 5 is improved. be able to. Therefore, the strength of the fitting portion between the primary water-stopping material 4 and the secondary water-stopping material 5 can be kept relatively low, and the assembling work between the water-stopping materials 4 and 5 can be easily performed. Moreover, each water-stop material 4, 5 and the holding | maintenance clip 6 may be integrated previously in a factory, and the construction effort at a construction site may be abbreviate | omitted. In this case, since each member is fitted, there is no fear that each water-stopping material 4, 5 is displaced in the longitudinal direction during transportation or the primary water-stopping material 4 is detached from the secondary water-stopping material 5.

そして、図７及び図８に示すように、各止水材４、５と一体化した保持クリップ６を外部側から目地３に押し込む。このとき、第７幅Ｗ４は、目地の幅Ｗ１よりも広く形成されるので、保持クリップ６の弾性板６４は、壁パネル２の小口面２ａに当接して弾性変形しながら目地３の内部へ圧入されていく。   Then, as shown in FIGS. 7 and 8, the holding clip 6 integrated with the water blocking materials 4 and 5 is pushed into the joint 3 from the outside. At this time, since the seventh width W4 is formed wider than the joint width W1, the elastic plate 64 of the holding clip 6 contacts the small edge surface 2a of the wall panel 2 and elastically deforms into the joint 3 while being elastically deformed. It is press-fitted.

そして、図１に示すように、各止水材４、５と一体化した保持クリップ６を、１次止水材４の蓋部４ａが壁パネル２の化粧面２１に当接するまで目地３に押し込む。このとき、図２に示す第２幅Ｗ３は、目地の幅Ｗ１よりも幅広に形成されるので、ヒレ部５ａが弾性変形して外壁板の小口面２ａに圧接する。また、保持クリップ６の引掛片６５は、その幅Ｗ５が目地の幅Ｗ１よりも幅広なため壁パネル２の小口面２ａに引掛かって係止し、各止水材４、５が目地３から脱落することを防止する。そして、図２に示す第１幅Ｗ２は、目地の幅Ｗ１よりも幅広に形成しているため、図１に示すように、各止水材４、５と一体化した保持クリップ６を目地３へ押し込んでいくと１次止水材４の蓋部４ａが化粧面２１に跨って目地３を閉塞する。また、蓋部４ａは、幅方向の両端部を壁内方向へ向けて斜めに屈曲し、ヒレ部５ｂは、その先端部を壁内方向へ向けて斜めに屈曲しているので、壁パネル２と各止水材４、５との間に隙間を形成することがなく、壁内部への水の浸入を防止することができる。   Then, as shown in FIG. 1, the holding clip 6 integrated with each water-stop material 4, 5 is placed on the joint 3 until the lid portion 4 a of the primary water-stop material 4 comes into contact with the decorative surface 21 of the wall panel 2. Push in. At this time, since the second width W3 shown in FIG. 2 is formed wider than the joint width W1, the fin portion 5a is elastically deformed and press-contacts the small edge surface 2a of the outer wall plate. Further, since the hook piece 65 of the holding clip 6 has a width W5 wider than the joint width W1, the catch piece 65 is hooked and locked to the small edge surface 2a of the wall panel 2, and the water-stopping materials 4 and 5 are detached from the joint 3. To prevent. Since the first width W2 shown in FIG. 2 is wider than the joint width W1, as shown in FIG. When pushed in, the lid portion 4 a of the primary water blocking material 4 straddles the decorative surface 21 and closes the joint 3. Further, the lid portion 4a is bent obliquely with both end portions in the width direction directed toward the inner wall direction, and the fin portion 5b is bent obliquely with the tip portion directed toward the inner wall direction. And no water gap between the water-stopping materials 4 and 5, and water can be prevented from entering the wall.

なお、ここでは互いに隣り合う２枚の壁パネル２が同じ厚さである場合について説明を行ったが、図９に示すように、互いに異なる厚さの壁パネル２を使用することもできる。この場合、２次止水材５及び保持クリップ６がそれぞれの壁パネル２の小口面２ａの形状に応じて弾性変形することにより、目地３内部への水の浸入を防止することができる。したがって、例えば、建築物の修繕や増改築を行う際、新しい壁パネルと既存の壁パネルのそれぞれの厚さが異なる場合であっても、各止水材４、５及び保持クリップ６を目地３に圧入することによって壁目地の防水構造１を構築することができる。   Although the case where two adjacent wall panels 2 have the same thickness has been described here, wall panels 2 having different thicknesses can be used as shown in FIG. In this case, the secondary water blocking material 5 and the holding clip 6 are elastically deformed according to the shape of the small edge surface 2 a of each wall panel 2, thereby preventing water from entering the joint 3. Therefore, for example, when repairing or renovating a building, even if the thicknesses of the new wall panel and the existing wall panel are different from each other, the water-stopping materials 4 and 5 and the holding clip 6 are connected to the joint 3. The waterproof structure 1 of the wall joint can be constructed by press-fitting into the wall.

このように、本願の壁目地の防水構造１は、各止水材４、５を一体で成形せず別体で形成するので、各止水材４、５を従来よりも単純な材質や形状で製造することができ、製造コストを抑制することができる。また、設置される部位に応じて各止水材４、５を好適な材質とすることができるので、例えば、外気や室内環境の影響を受けやすい１次止水材４を耐候性のある材質とし、目地３の内部に圧入される２次止水材５を水密性に優れ、弾性変形し易い材質とすることができる。   Thus, since the waterproof structure 1 of the wall joint of this application does not form each water-stop material 4 and 5 integrally, but forms separately, each water-stop material 4 and 5 is simpler material and shape than before. The manufacturing cost can be suppressed. Moreover, since each water-stop material 4 and 5 can be made into a suitable material according to the site | part to install, for example, the primary water-stop material 4 which is easy to be influenced by external air or an indoor environment is a weather-resistant material. Thus, the secondary water blocking material 5 press-fitted into the joint 3 can be made of a material that is excellent in water tightness and easily elastically deformed.

なお、一体化した各止水材４、５及び保持クリップ６を分解する際は、上述した手順を逆に行うだけでよい。したがって、２次止水材５に外嵌している保持クリップ６を取り外し、１次止水材４を２次止水材５から引き抜いて各部材を分解することができる。そのため、経年劣化や損傷などによって各止水材４、５や保持クリップ６を取替える際に、各部材を容易に分別することができ、再資源化に繋げることができる。   In addition, when disassembling each water-stop material 4 and 5 and holding clip 6 which were integrated, it is only necessary to perform the procedure described above in reverse. Accordingly, it is possible to remove the holding clip 6 fitted on the secondary water stop material 5 and pull out the primary water stop material 4 from the secondary water stop material 5 to disassemble each member. Therefore, each member can be easily separated when replacing the water-stopping materials 4 and 5 and the holding clip 6 due to aging deterioration or damage, which can lead to recycling.

また、本発明の実施の形態は上述の形態に限ることなく、本発明の思想の範囲を逸脱しない範囲で適宜変更することができることは云うまでもない。   Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

この発明は、互いに隣り合う外壁パネルの間に形成される目地において好適に使用することができる。   The present invention can be suitably used in a joint formed between adjacent outer wall panels.
